In this study, Cu-TiC composites were successfully produced using hot
pressing method. Cu-TiC powder mixtures were hot-pressed for 4 min at 600,
700 and 800?C under an applied pressure of 50 MPa. Phase composition and
microstructure of the composites hot pressed at different temperatures were
characterized by X-ray diffraction, scanning electron microscope, and optic
microscope techniques. Microstructure studies revealed that TiC particles
were distributed uniformly in the Cu matrix. With the increasing sintering
temperature, hardness of composites changed between 64.5 HV0.1 and 85.2
HV0.1. The highest electrical conductivity for Cu-10 wt.% TiC composites was
obtained for the sintering temperature of 800?C, with approximately 68.1%
IACS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
